This thermostat, OEM T310-70, is engineered to open at 70 °C and is specified for ZMZ-409 engines as used in the Bukhanka Modern (2.7 L Injection). It also fits other UAZ vehicles equipped with ZMZ-405/406 engines, including Hunter & 469 (2.7 L), Patriot, and Profi models. By regulating coolant flow to the radiator, the thermostat ensures the engine reaches and maintains its correct operating temperature, improving efficiency, reliability, and cabin heating performance.
Why choose this 70 °C thermostat?
Unlike standard thermostats that may open later, this 70 °C unit is designed for faster coolant circulation and quicker engine warm-up, making it especially effective in colder climates or during heavy-duty use. Earlier coolant regulation not only improves passenger comfort by accelerating heater response but also supports stable engine operation when fitted with auxiliary loads such as winches, expedition gear, or additional cooling demands.

Installation tips:
Work only on a cold engine to avoid burns. Drain coolant below the thermostat housing level before disassembly. Remove the housing cover, clean mating surfaces, and insert the thermostat with the spring side facing the engine. Always install with a fresh gasket or sealant. Refill with recommended coolant mixture and bleed air from the system by running the engine with the heater on. Verify that coolant circulation begins at ~70 °C and that temperature stabilizes correctly.
When to replace?
Replace if the engine runs cold, overheats, or if cabin heat is delayed. A thermostat stuck closed causes overheating, while one stuck open prevents the engine from reaching optimal operating temperature. Installing a new 70 °C thermostat ensures consistent temperature regulation and long-term engine health.
